I'm having difficulties interpreting this. By high level, you mean game design? I read Masters of Doom too and it was a fantastic read. But for me what I really found interesting was how the "two Johns" were able to leverage their different personalities, skill sets and areas of focus in a way that allowed Id Software to become a world famous studio. Since I'm more of a technical guy, I found the glimpses into the business side of software / game development to be illuminating. In particular, I really got a kick out of learning about the "shareware" model of selling games - it's incredible the sums of money they were able to get just from that alone. Also it was interesting to see how once you've established a reputation for yourself in the industry it's easy to acquire capital for future ventures, even though the fundamentals of these new ventures may not be obvious. Perhaps it had something to do with the climate at the time (dot com mania) but the amount of venture funding John Romero and Tom Hall were able to secure for Ion Storm and how that capital was subsequently (wasted) is utterly mind boggling to me.
If you ask me John Romero made Eidos his b*h, not his fans!
